So I read a lot of PUA stuff, but apply very little and I think that is what has got me into this problem (I'm a college freshmen and summer is coming up):

I built attraction with this women but ended up letting it fizzle by concentrating too much on comfort (3 lunch "dates") without sexualizing it. I know from her friends that "she was interested", but at this point I'm either close to or in LJBF zone.
She still responds quickly to any text message flirting...and accepts invites to hangout
But, she never initiates contact, which is frustrating
My mistakes have been: not enough kino, not setting a sexual frame, and not kiss closing when I had iso and knew she wanted it (a month ago)
Is it too late to set a sexual frame without it seeming out of the blue

-we are in the same social circle, so bear that in mind

Whats my play here (I like her, but I can cut it if need be; I don't have oneitis, but I also don't have other options)
Choose a poll option and explain why or just post a different idea.

Thanks
P.S. I don't have much game and that's why I did not pull the trigger with all the IOIs when I did have isolation
